y LAwiv-EDGER.

T0 all whom it may concern Be it known that we, PETER IMHOE and WILLIAM J KELLY, citizens of the United States, residing in theV city and county of Denver and State of Colorado, have invented certain new and useful Improvements in Lawn-Edgers; and we do` declare the following to be a full, clear, and exact description of the invention, such as will enablefothers 'skilled in the art 'to which it appertains| to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

Our invention relates to improvements in lawn edgers, or devices for giving a nished appearance to the edge of the lawn adjacent walks, and whereby a trench or earth groove approximately V-shaped in cross section, is produced. HeretofO-re, so far as we are aware, the only instrument used in connection with this work is the ordinary spade, making the work very expensive because of the great amount of time required by the` v of the head of the device is formed, the saine gardener in properly accomplishing it.

The object of our invention is not only to facilitate the work, but' also to provide a device whereby the work may bebetter accomplished, as the edge may be made perfectly straight, while the walls of the trench or earth groove are made uniform and symmetrical; and to this end, the invention consists of a tool comprising a handle and a head member, the head consisting of two blades, one of which is vertically disposed whenk in use, while the other is inclined to the vertical and extends inwardly toward the vertical blade, the two blades being suitably spaced to form an earth groove or trench having a vertical wall and an inclined wall, the vertical wall being adjacent the walk and the inclined wall adjacent the lawn or on the lawn side of the groove or trench. These two blades are connected at the top by a'plate which is upturned at'one edge to fo-rm an angle shaped member which may be employed for cleaning out the trench after the work of the two blades has been accomplished. The handle is connected with the head in any suitable manner.

As illustrated in the drawing, the head of the device with the exception of a part form ing a socket for the handle, is formed vfrom an integral piece of sheet metal which may Specification of Letters Patent.

fore outlined, after'which the socket part isapplied and the handle connected therevwith in any suitable manner.

Having briey outlined ourl improvement, we will proceed to describe the same in de.- tail, reference being made to the accompanyingdrawing, in which is illustrated an em.

bodiment thereof.

In this drawing, Figure'kl` is .topA

plan fragmentary view illustrating a walk Y and an adjacent lawn, showing our improved device in position for use while formingv a trench or earth groove 'adja-V cent the walk. Fig. 2 is a similar view showing the tool in the reversed position,

and as employed for cleaning outthe` earth groove after the cutting operation has been accomplished. Fig..3 is a cross section taken on the line 3 3, Fig. l. y Fig. l is a similar section vtaken on the line l-'4, Fig. 2. Fig.` 5 is a cross section taken through the groove andV also cutting the walk and the adjacent part `of the lawn. Fig. 6 is a top plan view of the blank from which the bodyportion being shown on alarger scale than in the previous views. Fig. `7 is a side elevation of the tool, with the handle partly broken away, shown on approximately the saine scale as Fig. 6.` Fig. 8 isa section taken through the tool, on a plane cutting the handle vand its socket longitudinally. Fig.l

9 isa perspective view of a socket plateemployed in connection with the body of the head. Fig. 10 is a cooperating socket plate.

Fig. 11 is a section similar to Fig. 8, butV showing a slightly modified form of con? struction so far as-the socket of the device is concerned. Fig. l2'is a perspective view of the socket plate employed in connection with the form of construction shown in Fig. 1l.

Fig. 13 is a detail view in .perspective of.

the bodyvof the head ofthe device of the form shown in Fig. 11. Figs. 1l, 12 and 13 -are shown on a slightlyV larger scaleV than the,y

formed from a blank` 6 'composed of sheet'V metal and comprising a top plate 7, cutting blades 8 and 9, and a cleaning memberlO. In forming the head of the device from this iio blank, the meal isrbent on the doi-.ted iin@ 12, whereby the blade 8 is inclined inwardly, as it extends downwardly; and on the dotted line 13, whereby the blade 9 occupies a vertical position; while the plate is bent on the dotted line 14 whereby themember 10 extends upwardly above the top plate 7 or in a direction opposite the projection of the blades 8 and 9. To the upper surface of the top plate 7 is secured two upper and lower socket members 15 and 16, the upper socket member having an upwardly bent socket part 17, which coperates with a socket part 18 formed in the member 16, the metal of which is first bent upwardly as shown at 19, and then downwardly, whereby the entire socket 20 which is adapted to receive the lower extremity of the handle 21, occupies a position above the top plate 7 of the device. As illustrated in the drawing, the member 15 is recessed at one extremity as shown at 22, to allow a brace 23, with which the member 16 is provided, to extend upwardly therethrough. This brace is riveted to the member 10 of the device, as shown at 24:, while the members 16 and 17 are secured to the top plate 7 by passing rivets 25 or other suitable fastening devices, through registering openings 26, 27 and 28, formed in the members 15 and 16, and in the top plate 7. After the lower extremity of the handle has been inserted in the socket composed of two parts 17 and 18, a screw may i be passed through an opening 28 formed in the socket part 17, and threaded into the socket extremity of the handle.

1n the form of construction shown in Figs. 11 to 13, inclusive, a single socket plate 29 is employed, and the socket part 30 coperates with a socket part 31, struck up out of the top plate 7 of the head of the device. In this event, the member 29 is provided with a brace 32 and a securing lip 33, perforated as shown at 34C to receive a rivet 40 or other suitable fastening member. It is believed that this form of the device will be somewhat more economical to manufacture than the other form. As illustrated in Fig. 11, a pin 35 is passed through registering openings formed in the socket members 29 and 31, and in the part 36 of the handle, which enters the socket.

From the foregoing description, the use and operation of our improvement will be readily understood. Both forms of the device are used in the same manner. In the first place, the tool is used as illustrated in Fig. 1. The two blades 8 and 9 extending downwardly, the vertical blade 9 being adjacent the wall 37 of the inclined blade 10 on the lawn side thereof. Assuming that the device is placed in this position, (see Figs. 1 and 3) the user draws the head of the tool along so that the blade 9 is guided by the edge of the walk, until the cutting operation has been completed for a suitable distance. The position of the head will then be reversed (see Fig. 3), and the member 10 employed for cleaning out the trench, whose walls have been formed by the blades 8 and 9. This blade 10 has the shape approximately of the cross section of the groove 38.

From the foregoing description, it will be understood that the lawn edging function may be economically accomplished by our improved device, while at the same time, a much better job can be obtained than by the method and tools heretofore in vogue.

Having thus described our invention, what we claim is,-

1. A lawn edger comprising a top plate having downwardly extending spaced blades arranged on opposite sides, and an upwardly extending blade located at one end of the plate.

2. A lawn edger comprising a top plate having downwardly extending spaced blades arranged on opposite sides, and an upwardly extending blade located at one end of the plate, the shape of the upwardly bent blade conforming approximately with the cross sectional area of the space between the two downwardly bent blades.

' 3. A lawn edger comprising a top plate having downwardly bent side blades an ranged in opposing relation and suitably spaced, one of said blades being inclined to the vertical and extending toward the other blade, and an upwardly extending blade located at one end of the plate and having one vertical edge and another edge inclined to the vertical to conform approximately to the inclination of the inclined side blade.

A. A lawn edger comprising a top plate having side blades ex-tending therefrom in one direction, an end blade extending therefrom in the opposite direction, and a socket plate applied to the top plate.

5. A lawn edger comprising a top plate having side blades extending therefrom in one direction, an end blade extending therefrom in the opposite direction, and a socket plate applied to the top plate, and having an upwardly projecting brace secured to the end blade, substantially as described.

In testimony whereof we affix our signatures in presence of two witnesses.
